Two lesions were present, one in the right lobe and one in the left lobe (not shown). (A) Axial arterial phase MRI demonstrated arterially enhancing lesion measuring 5.1 cm. (B) Delayed coronal phase MRI demonstrates capsular enhancement. (C) Axial MRI obtained 6 months after the procedure...

Four insulinomas were histopathologically confirmed. Late arterial phase (LAP) images demonstrated the largest number of pancreatic nodules reaching the highest enhancement scores (n=13, 76%). All analyzed dogs had CT evidence of arterially enhancing nodules in the liver (n=12), seven in the ...
The MST was 18.3 months, PFS was 14.2 卤 6.2 months, and the 1-, 3-, and 5-year survival rates were 93.2% (55/59), 42.5% (17/40), and 27.2% (9/33), respectively.Conclusion: TACE + RFA is safe, feasible, and effective in enhancing the focal control rate and survival rate of...
Virtual monoenergetic images from spectral detector computed tomography facilitate washout assessment in arterially hyper-enhancing liver lesionsCarcinoma, hepatocellularTomography, X-ray computedDiagnostic imagingImage quality and quantitative washout parameters as well as subjective washout visibility and diagnostic...
To assess the prevalence of arterial phase (AP) ring-enhancing small hepatocellular carcinomas (HCC) on magnetic resonance imaging (MRI); detail additional MRI features that enable HCC diagnosis; and examine arterial timing as one possible cause of this appearance.Patients undergoing HCC screening ...
A semi-automatic 3D volumetric segmentation of dominant target-lesions was performed on MR images in the portal-venous phase of pre- and post-treatment MR. The amount of enhancing tumor tissue was measured using the quantitative EASL (qEASL) software and expressed as a percentage of the entire...
Free Hb or heme are potent local or systemic chelators of NO, enhancing SMC contraction and arterial vasomotor tone within tissue (vasospasm), or systemic hypertension [15]. Heme from free Hb scavenges NO and forms nitrosoHb, promoting the shift of Fe++ (ferrous) to Fe+++ (ferric), ...
(f) A multiphase coronal computed tomography in the portal phase image 1 month after B-TACE, demonstrating oily subsegmentectomy with dense lipiodol accumulation within the tumor (asterisk) and non-enhancing, hypoattenuating peritumoral liver parenchyma, indicating peritumoral parenchymal necrosis (...
